55.3Network adapter configuration

Network adaptors on home or business PC networks are normally configured to obtain an IP address automatically from the network to which they are connected. These address services are typically provided by an internet gateway or a server computer on the network. Although some sophisticated audio networks may have these services, a dedicated CobraNet network typically will not. Therefore, your network adaptor should be manually assigned an IP address in most cases.

55.3.1 IP address assignments

It is recommended to assign the following IP addresses for CobraNet networks.

•192.168.100.1 through 192.168.100.199 - CobraNet devices (Default IP addresses assigned by CobraNet Discovery)

•192.168.100.200 through 192.168.100.219 - Network switches and infrastructure.

•192.168.100.220 through 192.168.100.254 -

Computers

When following the above recommendations, your computer should be assigned an unused IP address in the range 192.168.100.220 through 192.168.100.254. See also section 32.8 about IP address limitations.

55.3.2 Manually assigning an IP address

1 From Control Panel, open Network Connections.

2 Right click on the Ethernet adaptor you will be using for connection to the CobraNet network and select Properties.

3Find Internet Protocol (TCP/IP) in the list of services.

4 Press Properties button.

5 In the Internet Protocol (TCP/IP) Properties dialog, select Use the following IP address.

6 Enter IP Address.

7 Enter 255.255.255.0 for Subnet mask.

8 Leave Default gateway blank.

9 Settings in the second half of the dialog box are unimportant for Discovery operation. It is fine to leave Preferred DNS server and Alternate DNS server fields blank.

10 Click OK on all dialogs to save settings. On Windows NT and 2000, you may be directed to reboot before new settings will take effect.

Note

To restore settings to automatic assignment at a later time, return to the Internet Protocol (TCP/IP) Properties dialog and select Obtain and IP address automatically.

55.4Operation

Make sure that the PC on which you installed CobraNet Discovery is connected to the CobraNet network, and is not behind a firewall. On the PC, go to Start > Programs

>CobraNet Discovery > CobraNet Discovery. Upon starting the program the PC shows the CobraNet Discovery window (refer to figure 55.1 for an example). Only one CobraNet Discovery program can be active at one time.

figure 55.1: CobraNet Discovery main window

The Discovery window is a dynamic display of devices found on the network. When a CobraNet device is added to the network, the device is added to the list. If a device is removed from the network or powered down, its status will change to off line but it will remain on the list until the display is manually reset with the Display Refresh (F5) operation or the application is restarted. If Discovery is started for the first time the devices do not show a valid IP address yet. Columns in the discovery window may be resized by dragging the boundaries between columns in the column heading area. Columns may be reordered by dragging the text area in the column heading area.

The discovery window contains default columns

S (Status), MAC Address and IP Address, that are always present and cannot be hidden or removed.

The information in these columns is obtained by passively monitoring communications on the network.
